Norbury's Victorian terraces and post-war semis often hide complex ground challenges beneath their foundations. From subsidence repairs to drainage overhauls, structural groundwork requires specialists who understand South London's clay soil quirks.
Response within 24 hours
Those charming Edwardian properties along Norbury Court Road didn't anticipate modern drainage demands when built over a century ago. Clay shrinkage, tree root damage, and ageing infrastructure create unique challenges across SW16's residential streets. Whether tackling waterlogged gardens near Norbury Park or reinforcing foundations affected by nearby railway vibrations, each project demands careful assessment of local ground conditions.
Modern groundwork techniques transform problematic plots into stable, functional spaces. Underpinning strengthens compromised foundations while French drains combat SW16's notorious surface water issues. Careful excavation preserves mature root systems whilst installing soakaways that meet current building regulations. Ground stabilisation methods vary dramatically between Norbury's hillside properties and the flatter terrain towards Pollards Hill.
Twenty years excavating beneath Norbury homes teaches you which streets suffer repeated subsidence and where Victorian builders cut corners. Local knowledge means anticipating problems before breaking ground, saving both time and unexpected costs.
Rated 4.9/5 from over 280 verified reviews
Foundation underpinning typically ranges £15,000-£25,000 for a standard bay, whilst comprehensive drainage solutions start around £3,000. Victorian terraces often require £8,000-£12,000 for full damp-proofing groundworks.
Absolutely - emergency response covers all SW16 addresses plus neighbouring CR7 areas including Thornton Heath and upper Streatham. Urgent subsidence or drainage failures receive priority attention.
Initial site surveys happen within 48 hours, with work commencing 7-10 days later once party wall agreements are secured. Smaller drainage projects often start within 5 working days.
All foundation work includes decade-long structural warranties backed by insurance. This covers both the underpinning itself and any related movement in the original Victorian brickwork above.
Clay soil requires specialised solutions - we typically recommend attenuation tanks or connection to surface water sewers where permitted. Percolation tests determine the most effective approach for each property's specific ground conditions.
